A. A scope

B. A flow

C. An operation

D. An event source

B. A flow

Explanation:
Correct answer is an operation. For each method of the RAML specification , REST connect module provide an operation.

8. 8. )}

C. 1. 1. trains:
2. 2. {(
3. 3. conductorIds map ((engId, index) ->
4. 4. train: {

8. 8. )}

Explanation:
Points to remember:
* XML must have a root element.
* XML only allows one root element
* To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output
* When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}
-{ } are defining the object
( ) are transforming each element in the array as a key/value pair
* The transformation to XML would fail if the above mentioned considerations were not taken into account.
* Thus the transformation script declares a root element as trains and wraps the data in “{( )}“.
Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.
I call this a "Wrap The Map" scenario. Hope it would help you remember !

Its primary function is to design and develop fully functional Mule applications in a hosted development environment.

What is the difference between a subflow and a sync flow?

A. No difference

B. Subflow has no error handling of its own and sync flow does

C. Sync flow has no error handling of its own and subflow does

D. Subflow is synchronous and sync flow is asynchronous

B. Subflow has no error handling of its own and sync flow does

Explanation:
Correct answer is Subflow has no error handling implementation where as sync flow has Subflow:
A subflow processes messages synchronously (relative to the flow that triggered its execution) and always inherits both the processing strategy and exception strategy employed by the triggering flow. While a subflow is running, processing on the triggering flow pauses, then resumes only after the subflow completes its processing and hands the message back to the triggering flow.
Synchronous Flow:
A synchronous flow, like a subflow, processes messages synchronously (relative to the flow that triggered its execution). While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow. However, unlike a subflow, this type of flow does not inherit processing or exception strategies from the triggering flow.
This type of flow processes messages along a single thread, which is ideally suited to transactional processing.
